Some studies suggest that alcohol can help extend your sleep if these sedative effects are timed with the early phases of sleep, since you’re more likely to fall and stay asleep sooner. But while this may be the case with lower doses of alcohol (lower than a standard drink), there’s evidence that your sleep quality may diminish over the course of the night—especially if you’ve had more than a low dose. As a does alcohol help you sleep general rule, Meadows said, people should aim to leave at least three to four hours between drinking and sleeping to avoid sleep disruption. “For the best sleep, try to have at least four alcohol-free nights every week,” Meadows said. Breathing problems — Since alcohol’s sedative effect extends to your entire body, including your muscles, it may allow your airway to close more easily while you’re asleep.

  • Animal data indicate that administration of GABAergic antagonists lead to
    increased REM (Sanford et al. 2003; Xi, Morales, and Chase 2001, 1999).
  • If your drinking is impacting your sleep or overall quality of life, you may want to make a change.
  • This issue creates a vicious cycle that will never leave a person feeling well-rested.
  • If that mimosa with brunch hits you particularly hard, it may be the result of circadian timing.

This deep, slow-wave sleep is critical to getting good-quality rest. However, rapid eye movement sleep (REM) is also a vital part of the sleep cycle, since it aids in mental restoration. Some people may find they can’t sleep after drinking or their sleep quality suffers, and the science backs up this reality. Yes, alcohol can make you drowsy and help you fall asleep, but overall, it results in poorer sleep quality throughout the night. Whether you have had one or multiple drinks, it’s best to wait for your body to fully process the alcohol before heading to bed.

Alcohol and Sleep

Cherries, along with nuts and oats, are a natural source of melatonin. Don’t toss and turn if you’ve gone to bed and haven’t fallen asleep after 20 minutes. Instead, get up, walk around a little, and do a quiet, relaxing activity in low light. Ambient sound or noise can help create a comfortable sleeping environment. White noise machines or apps can also drown out sounds from outside.

Drinking a small amount of alcohol may help people fall asleep more quickly initially, but over time, individuals will need to consume more alcohol to achieve the same effect. Later in the night, as alcohol levels drop, your brain kicks into overdrive. “As the levels decline, you’re going to get more issues with the fragmentation,” said Dr. R. Nisha Aurora, a member of the board of directors of the American Academy of Sleep Medicine. You’ll also probably have more vivid or stressful dreams and — because fitful sleep means that you’re waking up more regularly — you are more likely to remember them.

Other general adverse effects

“REM sleep is critical to healthy brain function as it is essential in emotional regulation and the consolidation and retention of memories,” says Dr. Willeumier. Your body alternates between REM (rapid eye movement) and non-REM sleep in cycles of about 90 minutes. “Deep sleep” is a form of non-REM sleep — and, as mentioned above, it’s the time when your body focuses on rebuilding tissue, bone, and muscle, and strengthens the immune system. But REM sleep (during which you dream) is also very important, moreso for your brain. The researchers describe the effects of REM as “defragmenting the drive” — getting too little affects memory and concentration.

  • The problem is that while alcohol is boosting deep sleep, it’s also reducing REM sleep.
  • Research has shown that those who drink large amounts of alcohol before bed are more likely to take less time to fall asleep, but are also more likely to experience sleep disruptions and decreases in sleep quality.
  • You may wake feeling tired, groggy and not well rested—even if you seemingly slept the entire night.
  • Don’t bring work to bed; designate at least an hour off to relax and wind down.
